Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting connection, in particular to a PP pipe fitting connection device. Background Art

[0002] There are many ways to connect pipe fittings, the most common ones include the following: Threaded connection: Use threaded pipe fittings for connection, mainly suitable for galvanized steel pipes with a diameter less than or equal to 100mm, and steel-plastic composite pipes, mostly used for exposed pipes. Connection: This method is often used for pipes with larger diameters, generally used in main road connection valves, check valves, water meters, water pumps, etc., as well as pipe sections that need to be frequently disassembled and repaired. Welding connection: Suitable for non-galvanized steel pipes, mostly used for concealed pipes and pipes with larger diameters, such as electric welding connection, argon arc welding connection and manual welding connection. There are many ways to connect pipe fittings, and the choice of which method depends on factors such as specific pipe materials, pipe diameters, use environment and installation requirements. In actual applications, choose the appropriate connection method according to the specific situation and ensure the quality of the connection to ensure the safe, stable and efficient operation of the pipeline system.
